#4632 MEN1 associated pancreatic neuroendocrine tumours: Re-evaluating the 2cm cut-off for surgical resection

Introduction: Pancreatic neuroendocrine tumours (PanNETs) are the leading cause of death in patients (pts) with MEN1. Screening is recommended to diagnose early and prevent metastases. The optimal cut-off of when to intervene in a PanNET is still an area of debate.

#4322 Clinical outcomes of patients with rectal neuroendocrine tumours smaller than 10mm after endoscopic resection

Introduction: Rectal neuroendocrine tumours (r-NETs) generally have a good prognosis, but up to 20% may be misdiagnosed during endoscopy, risking inadequate treatment. Prognosis factors include tumour size, grading, staging, and lymphovascular invasion, with guidelines recommending endoscopic resection for small, low-grade lesions.

#3385 Review of appendiceal neuroendocrine neoplasms and pathological features that influence decision for oncological right hemicolectomy

Introduction: Appendiceal neuroendocrine neoplasms (NEN) are typically an incidental finding with 80% diagnosed post-appendectomy in the setting of acute appendicitis. While ENETS recommends that patients with appendiceal NEN >2cm undergo right hemicolectomy (RH) there is uncertainty in how to manage those measuring 1-2cm.

#2714 The Clinical Outcome of Non-Curative Resection of Small Rectal Neuroendocrine Tumours

Introduction: Small rectal NETs are thought to be less aggressive and relatively benign. However, lymphovascular invasion(LVI) or positive margin after endoscopic resection(ER) was noticed in small rectal NETs.
